Title: Improvement in the manufacture of grinding or abrading tools
IPC: B24D3/08
Filed: 1920-07-31
Abstract: 149,686. Mayer, F. Jan. 24, 1919, [Convention date]. Wheels and other tools.-In a grinding-tool having the abrading-mtaerial embedded in a metallic support, the supporting-medium consists of aluminium, and the abrading material comprises substances which, being fused with the aluminium, separate out on cooling in the form of crystalline bodies, for example, iron-zinc alloy, iron silicide, silicon, &c. To vary the hardness &c. of the tool, the quantity of the crystal-forming substance is varied; the size of the masses of crystal can also be controlled by control of the heating. The tools may be in the form of hollow bodies or formed with hollow cores of iron. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of a mixture of the crystal-forming substance with the raw material from which aluminium is separated. It is also stated that other alloys may be added to vary the hardness &c. of the tool. This subjectmatter does not appear in the Specification as accepted.

Title: Improved manufacture of fodder
IPC: A23K10/38
Filed: 1926-09-16
Abstract: 275,434. Kienzle, A. E. Sept. 16, 1926. Food for animals.-Maize cobs, either complete with or freed from the grains, are ground and mixed with wet brewery residue consisting of spent malt containing some beer; other wet or dry foodstuffs may be added subsequently. By drying the mixture it may be rendered stable. Suitable proportions are 75 parts by weight of dry maize cob flour, groats, or flakes with 25 parts of ordinary wet spent malt. Average grinding only of the maize material is resorted to, so that an average degree of fineness only is obtained, whereby subsequent sifting produces classes having different proportions of nutrient material. Molasses constitutes a suitable addition to the fodder; for the highest food value, the complete maize cob with its grains is ground. The interaction is such that the fodder may be given in unlimited quantities, which is not the case with brewery residues alone. Prior fodders are mentioned consisting of ground maize stalks mixed with swill from breweries, and of brewers' grains with hay or straw chaff, or maize and other meal.

Title: Ringing current repeaters
IPC: H04Q1/442
Filed: 1951-10-03
Abstract: 719,139. Repeaters. AUTOMATIC ELECTRIC LABORATORIES, Inc. Oct. 3, 1951, [Jan. 16, 1951], No. 23066/51. Class 40 (4). In a voice-current repeater with arrangements for repeating ringing currents, a magnetic amplifier is controlled by rectified incoming ringing currents to operate a relay which connects a local source of ringing current to the outgoing conductors. In a twoway arrangement, two trunk circuits 14, 15a are interconnected by a voice current repeater 15 which does not transmit the ringing currents. Ringing currents on conductor T1, R1 are rectified at 86 and are used to saturate the core of a magnetic amplifier 82. The output coils 96, 97 are connected to a source 16 of ringing current and to an A.C. relay 60 which operates when the amplifier core is saturated. Relay 30 follows 60 and connects a source 17 of ringing current to the outgoing trunk circuit 15a. A relay 50 disables the rectifier 87 and the magnetic amplifier 83 which cannot then repeat currents in the opposite direction. Relay 50 is slow-torelease so that ringing currents cut off when 30 falls back have time to die away before the rectifier 87 and amplifier 83 are ready to receive.

Title: Improvements in vapour generators
IPC: F22B29/02
Filed: 1947-08-20
Abstract: 648,011. Forced-flow steam &c. boilers; feedwater supply systems. FOSTER WHEELER, Ltd. Aug. 20, 1947, No. 23085. Convention date, Aug. 20, 1946. [Class 123(ii)] In a steam &c. boiler A fired by a burner 11, feedwater from a supply tank B is forced by a pump 26 through a pipe 25 and valve 27 to an economizer 22 and evaporator 19 to a separator C<SP>1</SP> of the kind described, for example, in Specification 559,439; from the separator C<SP>1</SP> steam flows to a superheater 28, fitted with a desuperheating water inlet 30, and water through pipes 83, 57 to a second evaporator 15 and separator C<SP>2</SP>, the steam from the latter separator also flowing to the superheater 28 and the water through a pipe 183 back to the pipe 57 for recirculation through the evaporator 15. As shown, each separator comprises essentially a vertical shaft 47 fitted with water turbine blades 51, water circulating pump blades 56, steam separating blades 67 and steam turbine blades 75, and the arrangement is such that, at starting, the shafts 47 will be rotated by feedwater from the pipe 25 which flows first through a valve 89 to the turbine 51 of the separator C<SP>2</SP> and thence through a pipe 54 and second valve 89 to the turbine 51 of the separator C<SP>1</SP> and back to the tank B through pipe 84. As steam generation increases however, rotation of the shaft 47 will be effected by the steam acting on the turbine blades 75, the relative quantities of steam respectively nowing through the latter and byepassing the same, being controlled by slide valves 79 in the steam outlets 76a, 76b. The valves 79, 89 of each separator are actuated by pressure-responsive diaphragms 80, 88 controlled by a nozzle 85 in the outlet water pipe 83 or 183, an increased flow through the nozzle 85, due to a decrease in the load and rate of evaporation, decreasing the flow of water to the turbine 51 and increasing the flow of steam through the steam outlet 76a and, hence, the turbine 75. Conversely, as the load and rate of evaporation increase, the steam flow to the turbine increases and the water flow to the turbine 51 decreases until, at maximum load, the water flow is a minimum.

Title: Improved anchorages for use in securing floors to concrete bases
IPC: E04B1/41
Filed: 1937-08-24
Abstract: 506,257. Floors; blocks. BIRCH, F. Aug. 24, 1937, No. 23134. [Classes 20 (iv) and 87 (i)] A device for use in supporting a wood floor on a concrete base comprises a metal tray having inwardly-inclined sides 10 whereby a cavity is formed having a dovetail-shape at all sections at right-angles to the base of the tray and having also keyways in the tray in the form of holes or openings 9 for the passage of keying-cement either when the tray is fixed in the floor or in the subsequent filling of the tray to hold a joint-supporting clip in place in the tray. The tray may be filled with an easily-removable material, such as wood-wool or paper, or it may be provided with a metal cover, to prevent the tray being filled with cement before fixing a joist-supporting clip therein. After the tray has been fixed in the floor, either by pressing it into the plastic concrete of the floor or by casting the concrete around the tray, the joist-supporting clip is secured in the tray by filling the latter with cement or concrete. This material will'either pass through any of the holes 9 which are still free, or key with the concrete which has passed through the holes 9 from the outside of the tray. Additional keying-means may be provided in the form of pockets 12 in the sides of the tray, or a downwardly-projecting rag-bolt. The tray may also be provided with legs 14, Fig. 6, to support it above a base-on which the concrete of the floor is to be cast. If desired, a number of trays may be threaded on a steel rod passing through the holes 9 in the sides of the tray. Concrete blocks may be provided with the trays embedded therein.

Title: Can treating apparatus
IPC: B67B1/00
Filed: 1966-05-24
Abstract: 1,091,279. Coating apparatus. STOLLE CORPORATION. May 24, 1966 [June 10, 1965], No. 23157/66. Heading B2L. [Also in Divisions B8 and F4] A can treating apparatus, which may wash, rinse, dry, and then coat cans, comprises a baffle plate having at its rear an endless chain conveyer on which can carriers are secured, the carriers projecting through a labyrinth passage in the baffle plate to the front of the latter, the carriers having holders in which cans to be treated are loosely secured. Jets of detergent, rinsing water, drying gas and coating material are directed onto the cans as they progress along the apparatus. The baffle plate 13, Fig. 6, is inclined to the vertical, with its upper edge projecting into the washing, &c., compartment. Each carrier 18 is secured to two parallel conveyer chans 16, and has a generally S-shaped section 18b projecting through a labyrinth passage in the baffle plate 13. A bar 19a on the forward side of each carrier 18 is formed with two can holders 19. Each can holder 19 comprises three equi-angularly spaced fingers 20 having outwardly-flared ends, and a pivoted latch rod 21 spring-biased to turn so that a locking finger 22 is projected inwards over a retained can. The cans fit loosely into the holders 19, so that they can turn in the holders under the action of the jets. The pivoted latches 21 each have cam fingers 23 at their inner ends, which as the chains 16 move forwardly, engage fixed cams 24 to turn the locking fingers 22 to a withdrawn position, and thus accept or release the cans. The conveyor chains 16 run over sets of parallel sprockets (15), Fig. 1 (not shown), which guide the chains in a generally sinusoidal path, and traverse the cans along a correspondingly shaped path within a housing (10) enclosing the machine. An electric motor (not shown) powers an intermittent drive mechanism (17), Figs. 2, 3 (not shown), and a shaft (14) to drive the chains (16), so that the cans move through the apparatus step-by-step. At the input end of the machine, cans are supplied pneumatically through tubes 25, Fig. 6, to the holders 20, the latches 21 at this point being turned to their withdrawn position by engagement of the cam fingers 23 with a fixed cam 24. As the cans progress through the apparatus, they are subjected on their bases to jets (29), Fig. 9 (not shown); on their outsides to jets (27); and on their insides to jets (30). At the output end of the machine, the pivoted latches 21 are again turned to their withdrawn position, and the cans slide out of the downwardly-inclined holders 19 into pneumatically-operated withdrawal tubes (26), Fig. 8 (not shown).

Title: Improvements in or relating to the frequency measurement of radio oscillations
IPC: G01R23/00
Filed: 1945-09-07
Abstract: 598,752. Wireless receiving systems ; preventing interference. JEFFERSON, S. Sept. 7, 1945, No. 23172. [Class 40 (v)] [Also in Group XXXVI] The frequency of a pulsed carrier is determined by heterodyning it at 11, Fig. 1, with a known oscillation from 12 to produce an intermediate frequency which is applied over a rejector circuit TRC, adjustable over a range including the intermediate frequency, to an intermediate frequency amplifier 14 and detector 15 feeding a cathode-ray oscillograph 17. In the absence of the rejector TRC, oscillator 12 is adjusted to give a maximum pulse trace P, Fig. 2, on the cathode-ray screen, but this is not a sufficiently precise indication of equality of the intermediate frequency to the tuning of the amplifier 14. The circuit TRC is then switched in so that the frequency response of it and the intermediate frequency amplifier becomes that shown in Fig. 5, and the oscillator 12 adjusted until the trace on the cathode-ray screen is as shown in Fig. 4, the peaks 21a, 22a being equal and the portion 23a, being as near zero as possible. Then the carrier frequency is given by the sum or difference of the frequency of the oscillator 12 and the frequency to which TRC is tuned. The circuit TRC preferably has its Q value reduced by retro-action over valve V2. When TRC is not required for frequency measurement it may be used for suppressing an interfering radiation.

Abstract: 1317481 Multiplex pulse-code signalling PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 13 May 1970 [16 May 1969] 23181/70 Heading H4L A time-division multiplex transmission system employing pulse-code modulation (for example delta modulation) in which one channel comprises an identifiable synchronizing pattern, includes at the receiver a shift register to receive the sync. pulse pattern and provide an output indicating substantial identity or not, this output in the case of a sequence of non-identity signals being used to interrupt the demultiplexing commutator in the receiver to enable searching of another channel for the sync. pattern. As shown, the pattern is generated at the transmitter by a recirculating register 39- 43 with modulo-2 adders 42, 43 providing a 7-bit reflating pattern, and a register 49 at the receiver provides an output representing the match between its contents and the transmitted pattern. If this exceeds a set level (e.g. not more than one bit in error) the stepping of the demultiplexing commutator 21 (corresponding to multiplexer 6 in the transmitter) proceeds normally under control of the clock recovery circuit 13. If however output from 49 repeatedly fails to reach this level a circuit 59 switches via circuit 62 a toggle 67 to halt for one clock period the advance of counter 24 controlling the demultiplexer so that a different channel is routed to 49 for testing. Fig. 2 (not shown) illustrates schematically the circuit 62. The system described has 16 channels (15 message plus one sync.) the clock 10 operating at 320 KHz.

Abstract: 760,809. Impulse transmitters. YANAGIDA, Y. Aug. 24,1953 [Aug. 23, 1952], No. 23345/53. Class 40 (4). A wanted number is set up manually on a plurality of digit-setting members, each of which carries a contact which co-operates with an associated set of fixed contacts; an impulsing drum is caused to rotate as many times as there are digits in the number, producing at each rotation a train of impulses corresponding to the setting of the relevant digit-setting member. As shown, a wanted six-digit number is set up on six discs 1, Fig. 2, made of insulating material and rotatably mounted on a common shaft 2 which is electrically conductive and is connected to the contacts 3 of which one is carried by each disc 1. Each contact 3 co-operates with a set of ten fixed contacts 4 which are connected to corresponding contacts 10 on a cylindrical plate 10A, Fig. 5, the contacts 10 being arranged in six rows of ten. Coaxial with the plate 10A is a drum 9, Fig. 6, of insulating material on which are mounted ten conductive strips 11, each of which has an extension 12 at one end. When the drum 9 is rotated, the extensions 12 engage the contacts 10 in each row in turn. In each row one contact 10 will be connected through associated contacts 4 and 3 and shaft 2 to one terminal of a battery 21 of which the other terminal is connected through ten electromagnet coils 18 to ten brushes 14 engaging the conductive strips 11. Thus the coils 18 corresponding to the settings of the discs 1 are energized in turn, bringing associated movable members 19 into the path of corresponding rings of contact members mounted on the surface of an impulsing drum 17. The numbers of contacts in these rings range from one to ten as shown and the drum 17 performs one complete revolution while the conductive extensions 12 on the drum 9 are moving from one row of contacts 10 to the next. The engagement of the operative members 19 with the contacts on the drum 17 sends the required impulses over the telephone line. Either of two substations 48 and 49 may be associated with the impulse transmitter by lifting the handset to operate a switch 28. A plurality of sets of discs 1 may be provided, each with a push-button switch to bring it into operation and start an electric motor which drives the drums 9 and 17. In a modification, Fig. 7 (not shown), the drum 9 with its conductive strips 11, 12 is replaced by rows of electromagneticallyoperated movable contacts controlled by the drum 17 so that each row is brought into engagement with its associated row of fixed contacts 10 in turn.
